PATENT, OFFICE BOTTLE GLEANINQBRUSH Application filed April 27,,

Our present invention has reference to a brush for cleaning the interiorof bottles, and our object is the provision of a collapsible brush forthis purpose of a construct-ion whereby the brush proper may be swungagainst the stem of a handle to permit of the insertion of the brush inthe bottle, and thereafter the brush is projected or extended from thehandle by the operation of a rod member which is pivotally associatedwith one of the brush sections and slidable on the handle so that thebrush may be brought to contact with all of the parts of the interior ofthe bottle, and by turning the same effectively clean the bottle in anyeasy and ex:

peditious manner.

To the attainment of the foregoing the invention consists in theimprovement hereinafter described and definitely'claimed.

In the drawings:

Figure 1 is a side elevation of a bottle cleaning brush in accordancewith this invention.

Figure 2 is a similar view but showing the brush collapsed.

Figure 3 is a sectional view approximately on the line 33 of Figure 1.

Figure 4 is a sectional view approximately on the line 4:4 of Figure 1.

Preferably and as disclosed by the drawings the handle 1 of theimprovement is formed on one end of a stem 2. The stem is in the natureof a wire rod of a suitable size and strength and the sides of the rod,adjacent to the ends thereof, are flattened for a considerable distance,as indicated by the numeral 3.

The brush is in the nature of a frame which is made up of jointedsections and preferably all of the sections are U-shaped in crosssection. For distinction the inner section of the brush is indicated bythe numeral 4, the said section having both of its ends bifurcated, andone of the bifurcated ends is offset and is pivoted, as at 5, to theflattened sides 3 of the stem 2. In the U-shaped frame section 4 thereis received and compressed a brush 6 which may be in the nature of apiece of felt or like material but obviously also may be of bristles.The second and normally outer 1931.

,section of the frameis indicated by the numeral' 7 and has its endreceived in and pivl otedat theouter end ofthe frame sectionfl.

The cross sectionally U -jshaped section7 carries a brush element 8 thatis clamped between the sides thereof. The outer or lower section [hasboth of its ends bifurcated and its outer end off-set and pivoted, as at9, to-the section 7, the second end of the lower sectionlO be- "ingpivoted, as at 11, to the flattened end3 of the stem 2; Thecrosssectionally U-shaped section 10 carries 'abrush element 12. Pivoted, asat 13, to thebrush or frame section 4 there'is the flattened end of arod 14. The rod, a-d acent its outer or free end is rounded upon itself,as at 15, and has its end formed with aneye; that receives therethroughthe stem2. The rounded portion 15 provides a finger hold for the rod,and the eye 16 holds the rod 14 against one side of the stem 2.

Obviously by moving the rodto the position disclosed by Figure 2 of thedrawings the brush frame will be collapsed and the sections thereof willbe folded against the flattened end 3 of the stem 2, the section 10 ofthe frame projecting therebeyond. This permits of the brush beinginserted in a bottle. When arranged therein the operator places hisfinger in the finger hold 13 and moves the rod 1 1 in the direction ofthe handle 1. This expands the brush. The brush is expanded to desiredextent to permit of the sections thereof being arranged at differentangles with respect to each other so that the brush can operate on theneck portion of a bottle and when the frame is in substantiallyrect-a-ngular position as disclosed by Figure 1 of the drawings thebrush can operate upon the bottom of the bottle. Of course, the bottleispartly filled with a cleansing fluid and the brush is rotated around theinterior of the bottle by the manipulation of the handle 1.

It is thought that the foregoing descri tion will fully andclearly setforth the-a van-' tages of the construction and the simplicity thereofso that further detailed description will not be required. Obviously wedo not wish to be restricted to the specific structure herein set forthand, therefore, hold ourselves entitled to make such changes therefromas fairly fall Within the scope of what we claim.

Having described the invention, we claim:

1. A bottle cleaning brush including a handle having a stem, a brushcarrying frame comprising jointed sections whose end members are pivotedto the stem, a rod guided along the stem and pivoted to one of the framesections at a point spaced from the stem and movable to collapse and toexpand the frame.

2. A bottle Washing brush, comprising a wire handle having a stemextending therefrom, and the said stem, from its outer end having itssides flattened, a brush frame comprising jointed sections which areU-shaped in cross section and which have brush elements received andclamped therein, said frame including an upper section which has anoffset end that is bifurcated and pivoted to the flattened portion ofthe stem anda lower end which has its outer end offset, its

inner end also being pivoted to the flattened portion of the stem, andan outer frame section which is pivotally secured to the upper and lowerframe sections, a rod having one end pivoted to the upper frame sectionat a point spaced from the stem, and having its opposite end roundedupon itself and merging into an eye that receives therethrough the stemof the handle.

In testimony whereof we afiix our signatures.
